Description

Handheld device for transferring a filmstrip

The invention relates to a handset for transferring a filmstrip from a belt to a substrate, comprising a housing from which a filmstrip transfer section projects outwardly, and in which a filmstrip supply spool from which the filmstrip transfer belt is drawn over the transfer section , And a take-up reel, preferably coaxial with the supply reel, are rotatably mounted and for torque transmission from the supply reel to the take-up reel, a slip clutch is provided, wherein on the Aufwiekelspule the empty tape is wound after transferring the film strip on the transfer part.

Such a hand-held device, namely for transferring an adhesive film from a carrier tape to a substrate, is known from DE 196 05 811 C1; Comparable handsets are used to transfer a correction material filmstrip onto a paper substrate to cover thereon parts such as characters or lines. Examples of such handsets, also called "correction rollers", are disclosed in WO 97/46475 A and WO 99/37569 A.

When transferring a filmstrip to a substrate by means of the transfer part of such a handheld device, the problem arises that the handheld device with its housing be held and guided uss, whereby it comes easily to an unwanted sideways tilting of the housing, which in turn u.a. results in insufficiently tight pressing of the filmstrip onto the substrate. In WO 99/37569 A has already been proposed a pivotal mounting of the transfer part in the housing, whereby the transfer part can always be kept flat on the substrate; however, this results in a relatively elaborate construction, but nonetheless it depends solely on the exercise of the person using the handset, such as when transferring the filmstrip to a substrate on this filmstrip

- By the transfer part - applied pressure is. This disadvantage also applies if the film strip to be transferred is an adhesive film which is present on a carrier strip and is transferred from the latter by means of a transfer part to the substrate, cf. in addition to the aforementioned DE 196 05 811 C and DE 36 38 722 C. To a lesser extent, this applies if a film strip is present without carrier tape and as such as in the form of a self-adhesive strip is transferred to the substrate, as disclosed for example in DE 30 25 345 C, or when labels are detached from a carrier tape and transferred to a substrate, such as in the devices according to US 5,806,713 A and US Pat. No. 6,029,849 A. The hand-held device shown in DE 36 38 722 C (similar to the hand-held devices according to US Pat. No. 3,839,127 and EP 104 989 A) also has a bottom area facing the substrate when the adhesive strip is transferred however, it may then be difficult to apply controlled pressure to the transfer member and over it to the adhesive strip so that the adhesive strip would adhere poorly to the substrate. On the other hand, in the devices according to US Pat. No. 5,806,713 A and US Pat. No. 6,029,849 A drive rollers are provided on the underside of the device which are provided for frictionally transporting the carrier strip through the device. These drive rollers must therefore be pressed particularly when using the devices on the substrate to drive them when moving the device rotating; it is a problem at the same time press the transfer edge uniformly on the substrate, but this is less critical in the relatively stable, having a body labels than a thin film material, in particular correction material in which an uneven pressing immediately to a poor covering of the leads desired substrate region.

A different type of handset is finally known from JP 5-318989 A; this device is used to transfer characters from a tape to a substrate, wherein each one tape section, pressed by means of a wide roll, cut with a blade and finally detached by leaving the characters from the substrate by hand. The device also has two lateral rollers at the rear end of the housing, which, however, make it difficult to evenly transfer the band sections due to their position.

It is an object of the invention to provide a handset of the type specified, in which in a simple manner a uniform, uniform pressing of the film strip is achieved on the substrate over the strip width, without a pivot bearing of the transfer part is necessary, and in which the Pressure on the transfer section when transferring larger strips fenlängen can be kept well constant, without requiring a special exercise on the part of the user is necessary.

The inventive handset of the type mentioned above is characterized in that at the time of transferring the film strip to the substrate substrate facing the lower side of the housing in the transition region between a transfer part receiving the housing part and the coil receiving housing part a tilt bearing defining support on both sides of the housing Main mid-plane is provided, which together with the transfer part results in a three-point support on the substrate. In this embodiment, the above object is met in an advantageous manner, and it is by the "three-point support" stable, uniform guidance of the handset when transferring the film strip to the substrate, ^' without undesirable lateral tilting of the housing in the transfer section, achieved , wherein the transfer part always rests flat on the substrate, even if it is rigidly arranged in the housing. Of course, the supports do not have to be exactly punctiform, but they may be formed by line-shaped, possibly even area-like areas, which naturally lie in one plane and should not be too large (too wide) in order to avoid the "three-point" Auflager "can result; Moreover, these support areas of the support for the housing form a tilting bearing with an axis about which the housing - which acts as a handle or gripping part - can be tilted to press the transfer part onto the substrate; by the given lever length - corresponding to the distance between the transfer part, in particular its transfer edge in the case of a wedge-shaped transfer part, and also before that area where the device is taken, namely in front of the coil receiving housing part, located tilt axis - the pressure can be good being controlled.

When transferring the film strip onto the substrate, as usual, the hand tool is moved over the substrate, wherein it rests on the substrate except for the transfer part and also the supports projecting downwards from the housing. In order not to hinder the movement over the substrate, the supports should be able to be moved as smoothly as possible over the substrate, and for this it is advantageous if the support by at least one integrally formed on the housing, relative to the housing preferably widened sliding surface is formed. It is favorable for the desired tilting of the housing to the sliding surfaces for the controlled pressing of the transfer part, further, when the sliding surface in the form of (in device longitudinal direction) arcuate skids is formed.

On the other hand, the movement of the handset over the substrate as well as the said tilting is particularly favored when the support is passed through at least one housing, e.g. on an axle, mounted roller is formed. As a result, when using the hand-held device not only a simple unrolling on the substrate is made possible, but it also favors such a role to a particular degree also a "tilting" of the housing with regard to a uniform pressing of the transfer part onto the substrate.

In this case, a structurally particularly simple design can be obtained if the roller is snapped into an undercut housing recess.

For controlled motion guidance in applying the filmstrip, such as when correction is to be made in the direction of application (i.e., a change of direction), it is advantageous if the support is formed by two rollers mounted laterally on the housing. It is also advantageous if the two rollers are placed on an axis passing through the housing axis. Furthermore, it is here for an efficient construction of advantage, if the axis inside the housing at the same time supports the transfer part.

On the other hand, it is also advantageous for a simple design of the housing when the two rollers are placed on separate lateral axes.

It is also favorable for the assembly of the roller (s) if the roller (s) are snap fit on the (respective) axis, or if the lateral rollers are inserted in undercut housing recesses, e.g. are snapped.

With regard to a particularly simple, well-suited for production by injection molding construction of the housing and the support is further particularly preferred when the rollers are arranged on a mounted on the underside of the housing axis. It can also be provided for easy mounting that the axis is snapped into provided on the bottom of the housing bearing extensions. It is also special for the production as well as for the assembly favorable, when the rollers with the axis in one piece, for example as an injection molded part, are formed.

The invention can be used with particular advantage in the transfer of correction material film strips from a carrier tape to the substrate, since a particularly uniform pressure is of importance here because of the sensitive, easily tearing material. As a precaution, it should be mentioned that the mechanisms to be provided with supply spool, slip clutch and take-up reel from the prior art, for example from the documents mentioned above WO 97/46475 A and WO 99/37569 A, are known per se, so that a such mechanism with a slip clutch, via which the Aufwiekelspule forth from the supply reel is driven so that the tape, which is withdrawn with the film strip towards the transfer part, by its pressing on the substrate, kept under tension and the same time from the supply reel driven take-up reel is transported, is not explained here. The take-up reel has a larger diameter than the supply reel, so that it must slip against the supply reel, wherein the slip torque in accordance with the tension of the tape, without this can break, is selected. In this case, supply reel and take-up reel can be arranged coaxially to one another, but they can also be accommodated on mutually parallel axis' and next to one another in the housing.

The invention will be further elucidated on the basis of preferred exemplary embodiments, to which, however, it should not be restricted, and with reference to the drawing. In this show in detail:

The hand-held device 1 shown in FIGS. 1 to 6 has a hand-shaped housing 2 serving as a handle, which usually consists of two shell-shaped housing halves (not shown in FIGS. 1 to 6, but see FIG. 13 or WO 97/46475 A) and in a narrower, front, wedge-shaped housing part 3 has a tongue-shaped transfer part 4 which protrudes in a conventional manner by an opening not shown in detail from the interior of the housing 1 in the front housing part 3 to the outside. This transfer part 4 has a front transfer edge 5, and via this transfer edge 5 runs a belt 6, which is unwound from a supply spool 7 contained in the interior of the housing 2 (see also FIG. The supply reel 7 is rotated when removing the tape 6 and drives via a in Fig. 10 only schematically illustrated slip clutch 8 a Aufwickelεpule 9, which has a larger diameter than the supply reel 7, and on the empty carrier tape 6 after transmission of the original on him existing film strip, eg from a white coating or correction material, onto a substrate 10 (see, e.g., Fig. 2).

FIG. 2 schematically illustrates a correction material film strip 11 already transferred to the substrate 10. The supply reel 7 and the Aufwiekelspule 9 are preferably coaxial with each other as known per se arranged (see also Fig. 10). 2, the handset 1 is moved to the right, in the direction of the arrow 12, when the filmstrip 11 is applied to the substrate 10. In order to achieve in this movement, the exercise of a uniform, well-controlled pressure on the transfer section 4 and its transfer edge 5 in order to detach the film strip 11 from the belt 6 and its complete, qualitatively flawless transfer to the substrate 10, wherein, moreover, an increased pressure Leverage is to be achieved is in the present handset 1 at a distance from the transfer part 4 on the bottom 13 of the handset 1 - ie on that side, which faces the substrate 10 in the use of FIG. 2 - a support 14 is provided with the the handset 1 is additionally supported on the substrate 10. In the embodiment according to Figures 1 to 6, this support 14 is formed by two rollers 16, 17 arranged on both sides of the main center plane 15 (see Figures 3 and 4). These two rollers 16, 17 roll when transferring the film strip 11 on the ^' substrate 10, with their contact areas 16', 17 'on the substrate 10 together with the transfer section 4 and with its transfer edge 5 a kind of three-point support on to the substrate 10, as also schematically illustrated in the bottom view in FIG. 7 in a somewhat modified embodiment, but with similar line-shaped contact areas 16 ', 17', and with the transfer edge 5 in total at 18. From the illustration in Fig. 2 is further clearly visible that when the handset 1 is tilted with its housing 2 about the rollers 16, 17 to the left, ie counterclockwise, according to arrow 19, the pressure on the transfer part 4th is increased, whereby by the leverage according to the lever with the distance between the rollers 16, 17 and the transfer part 4, a uniform, reinforced, well controllable pressure can be exerted. For this purpose, it is also important that both the transfer edge 5 and the support 14, ie the rollers 16, 17, are arranged substantially in front of that housing part 3 ', which is grasped during handling of the device by hand, namely that (Haupt -) housing part 3 ', in which the coils 7, 9 are housed. As can be seen, for example, from FIGS. 1 and 2, the support 14 is arranged in the transition region 3 "between the front housing part 3 (with the transfer part 4) and the coil receiving housing part 3 '.

From FIGS. 5 and 6 it can be seen that for attachment the rollers 16, 17 on the underside 14 of the housing 2, a bearing part 20 is integrally formed. This bearing part 20 has according to FIG. 5 on each side a one-piece axis 21 (in Fig. 5 is only one), and on these axes 21, the two rollers 16, 17 as shown in FIG. 6 in a snap fit (not illustrated in detail) attached.

The transfer part 4 can be easily rigidly mounted in the housing 2 due to the described three-point support 18, nonetheless a flat pressing on the substrate 10 can also be achieved by untrained persons.

According to FIGS. 7 and 8, the support 14 is a one-piece roller

22 is provided, which has a smaller diameter in its central region 23 and with this diameter-smaller area

23 is snapped into an undercut formed by two curved, flap-shaped housing extensions 24, 25 housing recess. The housing extensions 24, 25 thus form together with the remaining Aufnah opening in the housing circular arc-shaped bearing parts for the smaller-diameter, cylindrical roller portion 23. Laterally of the latter diameter-larger roller portions 26, 27 are present, the rollers 16, 17 in the embodiment of FIG 1 to 6 are comparable and form the described three-point support 18 together with the transfer part 4 or its transfer edge 5. The housing extensions 24, 25 extend essentially comparable to the roller bearing recesses 28 shown in FIG. 5 adjacent the bearing part 20, but in the middle region of the housing 2, on both sides of the center plane 15, and moreover over the center of the diameter-smaller roller region 23 defined circle so as to retain the roller 22 with its portion 23 in an undercut housing recess 23 ^' '.

In a comparable manner, it would also be conceivable, in the embodiment according to FIGS. 1 to 6, to snap the rollers 16, 17 into the bearing recess 28 instead of the axles 21 in undercut housing recesses. For this purpose, the bearing recess 28 would continue in the illustration of Fig. 5 only with a housing extension down over the circle center to come to the undercut shape.

In the embodiment of the hand-held device 1 according to FIGS. 9 and 10, the support 14 for the hand-held device 1 and for the abovementioned three-point support 18 is formed by skids 29, 30 which together define a sliding surface 31. The skids 29, 30 are formed on the housing 2 on the underside 13 laterally integrally formed outside, and they preferably have a curved bottom so as to facilitate the sliding and tilting of the handset 1 on the substrate 10.

FIG. 11 shows a modified embodiment of a hand-held device 1 with a single roller 22 as compared to FIG. 7, in that here this roller 22 is snapped onto a single axle 32. This axis 32 cantilevered out on a lateral housing flap 33 on the underside 13 of the housing, wherein on the opposite side a corresponding opening 34 in the housing 2 is provided, through which the roller 22 can be snapped onto the axis 32.

In the sectional view of FIG. 12, yet another form of the support 14 is shown, again with two rollers 16, 17, which are now - unlike in accordance with Figures 1 to 6 - snapped onto a single, continuous axis 32 '. this axis 32 'extends through a lower, narrower, central housing part 35 of the housing 2 and supports in its interior from the inside of the housing 36 existing portion 37 of the tongue-shaped transfer part 4 from which through the (not shown) front housing opening to the outside protrudes.

Finally, FIGS. 13 to 15 show a currently particularly preferred embodiment of the support 14 with rollers 16, 17 in a partial sectional view similar to FIG. 10, 11 or 12, the rollers 16, 17 having an axis This roller-injection-molded component 38 is fastened by snap-fastening on the underside of the housing 2 to lobe-shaped bearing extensions 39, 40 provided thereon, as shown in FIG. 14 in connection with the one bearing extension , these bearing extensions 39, 40 have a bearing recess 42 accessible from below via a narrowed slot opening 41. The rollers 16, 17 can also be designed to save material with recesses 43 or spokes 44, as shown in FIG In such a design of the rollers 16, 17, a slight suspension effect can be achieved, which has the desired control effect in the use of Handset additionally favors.

Finally, it can be seen from FIG. 13 that the Housing 2, as already mentioned above, in a conventional manner with two housing halves 2a and 2b is formed.

By way of derogation from the embodiments described so far, it is also possible to provide, for example, the or each roller - instead of being mounted on an axle with a snap fit - on the respective axle with the aid of a securing ring or the like. The rollers may be made of a relatively soft plastic material of relatively high friction, such as e.g. made of polyethylene. On the other hand, should the skids 29 in the embodiment of FIG. 9 and 10 or generally such a sliding surface 31 defining parts (as shown in Fig. 10, the two skids 29, 30 on the housing bottom 13 could be interconnected to a unitary sliding part) from a harder, low-friction plastic material, such as made of polystyrene.

Of course, it is also possible, instead of the shown coaxial arrangement of the forward coil 7 and take-up reel 9 to provide a biaxial coil arrangement.
